Abstract
A display substrate includes: a base substrate including a display area and a frame area on at least one side of the display area; a first transistor in the frame area including a first active layer; a second transistor in the display area including a second active layer at a side of the first active layer facing away from the base substrate, the second active layer including a first channel region; and a light shielding layer in the display area. The light shielding layer contains the same element as the first active layer. A material of the light shielding layer can absorb at least part of ultraviolet light and transmit part of visible light. An orthogonal projection of the light shielding layer on the base substrate covers an orthogonal projection of the first channel region on the base substrate.
